I have been nursing a frustrating hum for years now and thought I had tried everything (different leads, moving hardware, earth loops etc) and had given up on the thing, deciding to live with it rather than fret about it because in most cases you can't hear it on the finsihed track and because I am only sketching, not recording things for release.
Anyway, for no reason other than grabbing what was at hand, I used a new (expensive) lead on the weekend (one of the ones I gig with)and its a silent as a grave. It wasn't that I was using one bad lead. It was ALL of my leads that were cheap and probably bordeline microphonic (hence chaning the original set of leads had not cured the problem).
SO now I have to replace all of my leads with decent ones. More expense!

Worthy expense though - I have just upgraded my instrument cables and it has made a difference.
Are you using any compression or limiting on your bass recording...?
